BRAKE FOR TWO-WHEELED VEHICLES.

SPECIFICATION forming part of Letters Patent No. 669,135, dated March 5,1901. Application filed July 19, 1900. Serial No. 24,192. (No model.)

To all whmn it may concern:

Be it known that I, IVORY G. COLCORD, a citizen of the United States,residing at Des Moines, in the county of Polk and State of Iowa, haveinvented a new and useful Brake for Two-Wheeled Vehicles, of which thefollowing is a specification.

In training horses to attain speed in trotting or pacing there is greatdifficulty occasioned by trotting horses breaking into a lope and pacinghorses into a trot; and my object is to overcome such tendencies inhorses and to preventannoyances andloss oftime and speed and in manyinstances wagers that might be won by fast horses if such irregularmovements on the track were prevented.

Heretofore brakes have been combined with the thills of a vehicle andconnected with a hand-lever; but in no instance has a springactuatedtreadle been combined with brakeoperating mechanism mounted upon a baseadapted .to be detachably fixed to the thills of a sulky in such amanner that a person on the seat could thereby simultaneously apply thebrake-shoes to the wheels by foot-pressure advantageously while holdingthe driving-reins, as contemplated by my invention.

My invention consists in the construction, application, and operation ofa spring-actuated brake on a sulky, as hereinafter set forth, pointedout in my claims, and illustrated in the accompanying drawings, inwhich- Figure l is a top view of my brake adapted to be detachably fixedto the thills of a sulky. Fig. 2 is a front view of a sulky, showing thebrake applied thereto as required for practical use.

The letter A designates a straight fiat base made of wood or metal, uponwhich the brake mechanism is mounted. Metal clasps B,adapted to engagethe thills of a sulky, as shown in Fig. 2, are fitted to the under sideof the end portions of the base A and provided with elongated slots,adapting them to be adjustably connected with the thills by means ofscrew-bolts 0, extended down through perforations in the base A and theslots in the flat end portions of the clasps B, to be clamped fast bymeans of nuts d on the ends of the bolts or in any suitable way.

Levers H, carrying brakes J on their outer ends adapted to engage therims of the sulkywheels, are fulcrumed to the end portions of the baseA. Levers K, fulcrumed to the central portions of the base A, arepivotally connected with the inner ends of the levers H and alsopivotally connected with each other at their inner ends in such a manneras to produce a compound lever adapted for simultaneously applying thebrakes J to the snlkywheels by the foot-pressure of a person on thedrivers seat.

A spring m, fixed under the inner ends of the levers K, normally holdsup the inner ends of the levers K and depresses the inner ends of thelevers H, as required to hold the brakes J from contacting with the rimsof the sulky-wheels. By thus connecting the inner ends of the levers Kand fixing a spring between the base and the connected ends a treadle isproduced that can be readily operated by foot-pressure direct upon theconnected ends of said levers. A foot-pad m, that is convex on its underside, as shown in Fig. 1, may also be connected with the ends of thelevers to facilitate the operation of the brake.

By placing a foot upon the inner and connected ends of the lovers J theinner ends of the levers H will be elevated and the brakes J will bepressed against the rims of the sulky- Wheels, as required, to effectthe action of a horse hitched to the sulky, and such checking resistanceto the motion of the horse will arrest the loping of a trotting horseand the trotting of a pacing horse and also serve as a means to preventsuch actions of horses on a race-track.

Having described the construction, purpose, application, and operationof my invention, its practical utility will be obvious to personsfamiliar with the art to which it pertains, and

hat I claim as new, and desire to secure by Letters Patent, is

1. An attachment for sulkies comprising a straight flat base adapted tobe placed on top of the thills, adjustable clasps on the under' sides ofthe end portions of the base adapted to engage the thills, leverscarrying brake-shoes at their outer ends fulcrumed on top of the endportions of the base, levers pivotally connected with the inner ends ofsaid brake-carrying levers and fulcru med on top of the central portionof the'base and pivotally connected at their inner ends and a springfixed to the base under said ends to produce a spring-actuated treadle,arranged and combined to operate in the manner set forth for thepurposes stated.

2. An attachment for sulkies comprising a straight flat base adapted tobe placed on top of the thills, adjustable clasps on the under sides ofthe end portions of the base adapted to engage the thills, leverscarrying brake-shoes at their on te'r ends fnlcrn'm'e'd on top of theend portions of the base, levers pivotally connected with the inner endsof said brake-carryin; levers and fulcrnmed on
